A mod that adds a contractor link between 2 players similar to Beatrice and Subaru!
Spirit Contract: Return by Death
One of you is Subaru. The other is Beatrice. Good luck.
I wanted to play Minecraft with a friend the way Subaru and Beatrice go through Re:Zero: tied together, one of them dying over and over, the other one keeping him alive with magic. So I made this.
One player is the Contractor. The other is their Spirit. When the Contractor dies, they don't respawn. Time goes back about two minutes, for everyone. Your inventories, the blocks you broke, the chest you just looted and the creeper that blew you up all go back to how they were. You get to try again.
It's server-side only. Install it on the server and anyone can join with a normal 1.21.1 client. It also works in singleplayer and LAN.
How it works
Return by Death
- When the Contractor dies, the death is cancelled and the whole world rewinds about 2 minutes:
- every player's position, inventory, ender chest, health, hunger, XP and effects
- every block that was placed, broken, blown up or flooded
- chest, furnace and other container contents
- mobs, dropped items, boats, minecarts and item frames
- time of day and weather
- You hear a heartbeat and a deep bell, and the world goes dark for a moment.
- Save points work like the show. The moment you come back to becomes your save point. Die again quickly and you go back to that same point, never further. Live past it for 2 minutes and it moves forward.
- After a rewind, everyone gets a few seconds of immunity and no fall damage until they land. A rewind can't kill you again right away.
The Spirit
- The Spirit is about chest height on the Contractor.
- Your spells run on the Contractor's mana, which is their XP levels.
- Stay within 500 blocks of your Contractor. Wander off and you get a warning, then 3 minutes to get back before you fade away. The timer pauses if the Contractor logs off.
Gate mana (passive XP)
- While the Spirit is online, the Contractor's XP bar slowly fills on its own, about 1 level every 8 seconds.
- Subaru's mana gate isn't built for this. If his passive levels go over 100, he dies (and time rewinds).
- Spending mana on spells drains the gate back down, so your Spirit has to keep casting.
The Forbidden Library Tome
- The Spirit gets a glowing book when the contract is formed.
- Right-click it to open the spell menu. It has four tabs, and hovering a spell shows what it does and what it costs.
- Sneak + right-click recasts your last spell without opening the menu.
- While you hold it, the Contractor's mana shows above your hotbar.
Spells work on people too
- Attack spells hit hostile mobs and other players (if PvP is on). They never hit you or your own Contractor.
- Support spells help whoever you're looking at, or your Contractor if you're not looking at anyone.
The Witch's taboo
You can't talk about Return by Death.
If the Contractor tries to say it in chat ("I died", "return by death", "time loop", "rewind"…), the message never gets sent, and the Witch reaches for everyone within 10 blocks.
- Each of them gets a dark screen with a pounding heartbeat and has 5 seconds to click their own heart 4 times. It jumps around, and closing the screen doesn't save you.
- Miss it and you die.
- If nobody's close enough to hear, the Witch takes it out on the Contractor: he drops to 1 heart and stays slowed until he's fully healed.
/msg,/meand/saydon't get around it either.

Commands
/contract and /lifechain are the same command, so use whichever you like.
For operators
| Command | What it does |
|---|---|
/contract link <contractor> <spirit> |
Forms a contract. The spirit gets the Tome |
/contract unlink <spirit> |
Breaks a contract (works on offline players) |
/contract list |
Shows every contract on the server |
/contract passive <contractor> [levels] |
Shows or sets someone's gate mana |
/contract perf |
Shows how much the rewind system is costing the server |
For everyone
| Command | What it does |
|---|---|
/contract status |
Who you're contracted to, and your gate mana |
/ability |
Opens the spell menu (same as right-clicking the Tome) |
/ability focus |
Gives you a new Tome if you lost it |
/ability <id> |
Casts a spell directly (IDs are in the tables above) |
Quick start
- Install Fabric Loader and Fabric API for Minecraft 1.21.1 on your server.
- Drop this mod into the server's
modsfolder. - As an operator, run
/contract link <Subaru> <Beatrice>with your players' names. - The Spirit right-clicks the Tome, and you're off.
Good to know
- It's light on performance. The world is snapshotted every few seconds. On a normal server that takes a few milliseconds. If your world gets heavy, it automatically snapshots less often instead of lagging. Check
/contract perfif you're curious. - Rewind history lives in memory, so restarting the server starts it fresh.
- Some things can't be rewound. Mobs in chunks nobody is near, and players who logged out during those 2 minutes, stay as they are.
- Explosions don't play favourites. Al Goa and El Goa can hurt your own team, so aim carefully.
- Contracts and gate mana are saved with the world.
This is a fan-made mod. It isn't affiliated with Re:Zero, Tappei Nagatsuki, Kadokawa or White Fox. I just really like the show.
